In this lesson you will learn about nominal wall thickness and how it relates to designing functional plastic parts. Although parts can have various wall thicknesses to accommodate fit and function, designers are generally tasked with minimizing thickness to lessen material consumption, achieve a faster cycle time, and reduce manufacturing costs. But parts with thin walls are more challenging to manufacture. Difficulties can arise in molding, ejection, post-molding handling, and structural integrity. Let’s see how part designers can design a part with nominal wall thickness.
The first part of this lesson covers the importance of designing parts with nominal wall thickness, what factors play a role in determining nominal wall thickness, and how different materials and molding machine requirements impact nominal wall thickness.
